“…[106] This cell maintained a reversible capacity of ≈650 mA h g −1 , which is higher than the theoretical capacity of CuS 2 , implying that both sulfur and CuS 2 participate in the charge and discharge processes. In addition to CuS 2 , [106,107] TiS 2 exhibited a stable cycling performance, and the sulfur-TiS 2 composite showed achievable reversible capacities. [108] However, the capacity is relatively low due to Cu and Ti usage, resulting in a limited low energy density.…”

batteries based on intercalation materials cannot meet the demands of long-distance transport (i.e., >300 km).Recently, interest in Li-air [4][5][6] (or Li-O 2 as oxygen is the cathode active component) and Li-S batteries [7][8][9] has increased because of their high theoretical capacities and energy densities, which are suitable for remote transportation. Abraham and Jiang introduced the first rechargeable Li-O 2 battery in 1996, [10] although it drew little interest until Bruce and co-workers proved the rechargeability of Li 2 O 2 . [11] Li-O 2 cells possess significant strength because oxygen gas can be obtained from ambient air. Li-ions react with oxygen according to Equation (1), and Li 2 O 2 is the discharge product with an equilibrium potential of 2.96 V, delivering a large specific energy of 3600 W h kg −1 . Investigations on Li-S cell date back to the 1940s. The insulating nature of sulfur, Li 2 S 2 , and Li 2 S and the solubility of polysulfide intermediates greatly hinder its development. Fortunately, recent studies on new electrolytes and nanostructured material design provide merits and opportunities in developing Li-S batteries. Similar to Li-O 2 batteries, Li-S batteries, which contain inexpensive and abundant sulfur as positive electrode material, produce an average voltage of 2.15 V and possess a theoretical energy density of up to 2600 W h kg −1 , as further indicated by Equation (2). Many studies showed that intermediate polysulfide is produced during the discharge process where Li 2 S is formed as the final product. Typically, Li-O 2 and Li-S batteries both adopt Li metal as anode. The reason is that Li possesses the largest capacity (3860 mA h g −1 ) and the lowest negative electrochemical potential (−3.04 V) versus standard hydrogen electrodes. Thus, Li-O 2 and Li-S batteries are considered to be promising next-generation energy storage systems for PEVs and HEVs However, despite the advantages of Li-O 2 and Li-S batteries, they exhibit ignitability, toxicity, liquid leakage, and volatilization because of their organic liquid electrolyte components. Moreover, Li dendrites form during cycling, resulting in internal short circuit that leads to combustion and even cell explosion. [12,13] More seriously, the charging process in Li-air

“…The first introduction of the all-solid-state Li-S battery system was as early as the 1990s [352]. However, the prosperity of Li-ion batteries at that time resulted in the stagnation of Li-S and all-solid-state (ASS) Li-S batteries [31,353].…”

“…As for preliminary research, amorphous sulfide SSEs were firstly attempted in SS Li-S batteries, such as Li 2 S-SiS 2 glassy electrolytes and Li 2 S-P 2 S 5 glass-ceramic electrolytes [352]. In addition to the development of SSEs, investigation of cathode materials and an understanding of their electrochemical reactions in Li-S batteries were also studied.…”

Lithium-sulfur (Li-S) batteries have been considered as one of the most promising energy storage devices that have the potential to deliver energy densities that supersede that of state-of-the-art lithium ion batteries. Due to their high theoretical energy density and cost-effectiveness, Li-S batteries have received great attention and have made great progress in the last few years. However, the insurmountable gap between fundamental research and practical application is still a major stumbling block that has hindered the commercialization of Li-S batteries. This review provides insight from an engineering point of view to discuss the reasonable structural design and parameters for the application of Li-S batteries. Firstly, a systematic analysis of various parameters (sulfur loading, electrolyte/sulfur (E/S) ratio, discharge capacity, discharge voltage, Li excess percentage, sulfur content, etc.) that influence the gravimetric energy density, volumetric energy density and cost is investigated. Through comparing and analyzing the statistical information collected from recent Li-S publications to find the shortcomings of Li-S technology, we supply potential strategies aimed at addressing the major issues that are still needed to be overcome. Finally, potential future directions and prospects in the engineering of Li-S batteries are discussed.

“…These electrolytes have the great advantage of possessing lithium ion transport number of unity [131]. Amorphous 60Li 2 S·40SiS 2 (mol%) [132] and 80Li 2 S·20P 2 S 5 [131,133] are the examples of inorganic electrolytes evaluated in Li/S cells. Nagao et al prepared a sulfur composited that sulfur, carbon black and 80Li 2 S·20P 2 S 5 inorganic electrolyte were ball milled together to increase the intimate contact of electrode components, leading to the increase in cell capacity [133].…”

Lithium batteries based on elemental sulfur as the cathode-active material capture great attraction due to the high theoretical capacity, easy availability, low cost and non-toxicity of sulfur. Although lithium/sulfur (Li/S) primary cells were known much earlier, the interest in developing Li/S secondary batteries that can deliver high energy and high power was actively pursued since early 1990's. A lot of technical challenges including the low conductivity of sulfur, dissolution of sulfurreduction products in the electrolyte leading to their migration away from the cathode, and deposition of solid reaction products on cathode matrix had to be tackled to realize a high and stable performance from rechargeable Li/S cells. This article presents briefly an overview of the studies pertaining to the different aspects of Li/S batteries including those that deal with the sulfur electrode, electrolytes, lithium anode and configuration of the batteries.
